Working with Memory
I-modems contain three types of memory that you can interact with: random access mem-
ory (RAM), nonvolatile random access memory (NVRAM), and Flash memory.
RAM
RAM holds the settings that apply to the current conÞguration. Any changes you make are
active until you reset the I-modem or power it off.
NVRAM
NVRAM is user-conÞgurable. You can store, retrieve, and change settings in NVRAM.
Loss of power will not affect your settings.
Flash
Flash memory holds the I-modemÕs operating software. You can upgrade the software held
in Flash memory by performing a software download. (See Chapter 16, Do
wnloading
Software Upgrades.)
